请把下面的英文翻译成中文，，谢谢

我很高兴能缺课。按妈说，如果在我的肚子继续痛，我要缺课好几天。 我乐透了，但只能装作不开心和闷闷不乐。母亲相信我的戏。专业男女演员的戏都不能演得比我更好。
我的胃没有问题。 我是不能去上学，去面对大个子德里克。德里克比我高两班，比我高两英尺。 有一次他无意中听到我说他长了不少肌肉，但他妈忘了给他脑袋。他的脑袋和肌肉比我想象的更多，因为他全明白我说的，并能力把我在房间里摔来摔去。这成了他的日常活动。他会在学校找我和伤害我。如果我见到他而不迅速采取行动，并躲起来，大槪也没命告诉你关于我的问题。
我是积极地去解决问题的。但结果一波未平，一波又起。我请比德里克更大个子的比夫为我出头。当昨天比夫来到学校时，我才发现比夫和大个子德里克原是表兄弟。比夫和大个子德里克一并在操场上写道：“查理明天就会死。”由于上述发生的事故，我永远不能再回到学校。我已经接受了移居美国的念头。

原文如下：
I was happy to be absent from school. According to Mother, if the ache in my stomach worsens, l'll miss a few more days of school. I couldn't be happier but I had to act as if I was sad and upset. Mother believed my act. An actual actor or actress couldn't have achieved the level of acting I just did.
I actually didn't have a problem with my stomach. I couldn't go to school and face Big Derek. Derek was two grades above me and stood about two feet over me. It was an accident when he heard me say he had a lot of muscle but his mother forgot to give him brains. He had more brains and muscles than I thought because he had the ability to understand and throw me across the room. It became his daily activity. He would find me about school and hurt me. If I didn't act fast and hide when he came, I wouldn’t be able to tell you about my problems.
l was active in solving my problems. But I achieved nothing and gained more problem. I hired Biff who was much larger to give Derek a lesson. When Biff came to school yesterday, I discovered Biff and Big Derek were cousins. Together, Biff and Big Derek wrote across the playground, "Charlie will die tomorrow." Because of what happened above, I can never go back to school. I have accepted the idea of moving abroad to America.

初中的东西还要别人帮忙翻译，也是懒到极致了。

打字打出来再说
